Re: Depends on what you mean as incest.

I think when a father tries to use his daughter as a substitute for a full on sexual partner that is where things get fucked up. Sex play and trying to have a full on relationship are different.

There are many examples of parents sexually stimulating children in different societies and cultures. Studies of The Westermarck effect seem to look at marriage.

Sexual interaction can be fun and enjoyable and can happen without attraction. That depends on societies attitudes.

Those are valid points. Unfortunately, society doesn't tend to extricate sex play from seX-with-a-capital-X, if you see what I mean. These people barely understand our motives because they are, at this time, either truly oblivious or willfully ignorant (that is, unwilling to understand our motives.) So they are reacting to us at gut level much of the time, and their guts tell them to be repulsed. You have to understand: even MAPs often struggle with this. I have often had that horrific gut-sinking feeling when I've heard about certain pedophile cases myself, even though I am an MAP.

Now think of the feelings you've gotten when reading or hearing about incest cases, even when they were adults. Even if you've trained yourself to overcome these feelings, don't you sometimes still get that instantaneous reaction for the first few seconds after you hear of such a case? So imagine now how powerful that force can be in those who have no pedophilic or incestuous desires, and no personal stake in overcoming their revulsion to sexual liaisons they do not understand . . .

That's our problem, or one of them anyway. But it's a big one.
